Overcoming Water Treatment Challenges in the Power Generation Industry

Those in the power generation industry know how critical a reliable, steady stream of high purity water is. For power generation, water is used in high pressure boilers, turbines and cooling towers. Water treatment for power generation is a vital process that requires a dependable technology. High purity water ensures proper operation of steam generation system and reduces blowdown frequency and use of boiler chemicals. High purity water is also able to better protect against erosion and damage to equipment.

Desalitech’s Closed Circuit Reverse Osmosis systems excel where other RO systems fail and can provide maximum water recovery of up to 98% plus a resistance to fouling, scaling that drives your organization towards exceeding operational and sustainability goals.

CCRO allows plant operations to focus their on attention on more critical matters as the systems automatically adapt to varying feed water and allow for remote control of the system if there are changes that do need to be made.

Boiler Feedwater

When addressing water treatment for power generation, boilers require the highest quality water in the power plant. Allowing impurities to enter the boiler system can result in loss of heat efficiency, increased fuel consumption, condensate corrosion and reduced productivity. Desalitech’s Closed Circuit Reverse Osmosis systems reliably remove water impurities, guaranteeing consistent and highly efficient operation.

Cooling Water Blow Down

The cooling cycle is the largest consumer of water in the power plant. Efficient cooling water treatment is critical for ensuring maximum productivity and continuous operation. With greater scaling resistance and adaptability to varying feed water, Desalitech’s Closed Circuit Reverse Osmosis systems purify water at unparalleled levels of efficiency and reliability.

Zero Liquid Discharge (ZLD)

In regions where regulations limit the discharge of wastewater, reverse osmosis based ZLD solutions are becoming a cost effective option. Desalitech products are ideal for ZLD applications, achieving up to 98% water recovery, and by doing so, significantly reducing the high capital and operating costs of downstream evaporation, centrifuge, crystallizer processes.

About Us

Desalitech is removing the mechanical recovery limitation of traditional RO, while extending its chemistry induced limitations.

With ReFlex systems, recovery is determined by the frequency of the purge steps that are controlled by the operating software, and not by the mechanical design and the number of stages like in a traditional reverse osmosis system. Enter 98% recovery in the control panel, and the system will initiate a purge only when 98% recovery could be achieved.

Desalitech systems can extend recovery beyond the chemistry limitation of traditional reverse osmosis by exposing the tail membranes to the maximum concentration only for short intervals rather than permanently like traditional reverse osmosis.

Reduced Energy Consumption – Unlike traditional reverse osmosis systems that operate at constant high pressure, Desalitech systems start each batch at a low pressure which is gradually increased during the batch as concentration in the systems builds up. This leads to an average pressure which is lower than the constant pressure of traditional reverse osmosis. During the purge, the concentrate is discharged at the minimum pressure, rather than at maximum pressure like in traditional reverse osmosis process.

The combination of these factors typically results in a 20% to 35% reduction of energy consumption.

Resilience and Reliability – Desalitech systems are built with single stage short membrane arrays which allows for optimal flux distribution, a higher and more precisely controlled cross flow, and concentration variations that disrupt both scaling and organic fouling growth in the system.

Unlimited Flexibility and Adaptivness – Recovery, cross flow and flux are all interconnected in traditional reverse osmosis, but completely independent in Desalitech systems. In addition, they are all fully controlled and optimized by Desalitech’s operating software in real time. The same system can deal with completely different water treatment applications and behave completely differently for each – it can treat city water in the morning, reuse waste streams in the afternoon, and act as a second pass ultrapure system in the evening.

Standard, Certified Components – Desalitech systems utilize standard high quality reverse osmosis membranes and components, with the full warranty and performance guarantee of leading vendors such as Dow, Hydranautics, Grundfos and Allen Bradley. There is no specialty or noncompliant equipment or components to a Desalitech system, and the system can be operated and maintained either by your team, your existing service providers, or by Desalitech.

Trusted Source – Desalitech is the only trusted source for Closed Circuit Desalination or ReFlex reverse osmosis. Desalitech systems are covered by patents in dozens of countries around the world, and cannot be legally offered by anyone but Desalitech and its official partners.
